Hi,
I want to apply this condition on TT_wind_all_mashhad.wind_dir_remo.
if (value > 360) then (value-360) & if (value < 0) then (value + 360)
How can I do it ?

Let A be your array.
idx = A>360 ;
A(idx) = A(idx)-360 ;
idx = A<360 ;
A(idx) = A(idx)+360 ;

Before and after applying check the values with indices idx.

A = (A - 360) .* (A > 360) + (A + 360) .* (A < 0) + A .* ((A >= 0) & (A <= 360));
